Rent reviews are the process by which a landlord assesses whether the rent charged on an investment property still reflects current market conditions, and then adjusts it accordingly. Done well, a rent review protects your rental income, retains quality tenants, and keeps your property competitive in a fast-moving market.

For many landlords, rent reviews feel awkward. Nobody enjoys the conversation about raising rent, and the fear of losing a good tenant can cause years of below-market rents to accumulate quietly. Yet failing to review rent regularly is one of the most common and costly mistakes property investors make. This guide walks through exactly how and when to conduct a rent review, what the law requires, and how to benchmark the right figure with confidence.

When Should You Conduct a Rent Review?

Timing matters enormously with rent reviews. In Victoria, the Residential Tenancies Act 1997 (as amended) restricts rent increases to no more than once every 12 months for periodic and fixed-term leases. This means landlords have one window per year to make an adjustment, so missing it can cost real money over time.

The most logical moments to conduct a rent review are:

• At lease renewal — the natural break between one tenancy agreement and the next is the cleanest opportunity to reset rent to market.
• 12 months after the last rent increase — for ongoing periodic tenancies, track the anniversary date carefully and build a review into your calendar well in advance.
• After significant capital improvements — if you have renovated the kitchen, added air conditioning, or upgraded the bathroom, a post-improvement review is appropriate, subject to the 12-month rule.
• When the local rental market shifts sharply — CoreLogic data for Melbourne indicates that median rents across inner suburbs rose by approximately 8 to 10 percent year-on-year during 2023 and 2024. In a market moving that quickly, a landlord who skips a review can fall significantly behind within a single cycle.

Planning your review calendar 60 to 90 days before the review date gives you enough lead time to gather comparable rental data, issue the required notice, and allow the tenant time to respond or plan.

How Do You Benchmark the Right Rent Amount?

Setting the right rent figure is the analytical core of any review. A number pulled from thin air risks either losing a tenant unnecessarily or leaving income on the table. Solid benchmarking draws on several data sources simultaneously.

Comparable rental listings

Search current listings on Domain and realestate.com.au for properties of similar size, condition, location, and inclusions. Focus on properties that have been leased in the last 30 to 60 days, not ones sitting unsold for months. SQM Research’s weekly rental data and the REIV’s quarterly rental reports both provide suburb-level median rent figures that are useful as a cross-check.

Vacancy rates as a leading indicator

According to SQM Research, Melbourne’s inner-suburb vacancy rate sat at approximately 1.5 to 2 percent through much of 2024 and early 2025, well below the 3 percent threshold generally considered a balanced market. Low vacancy rates signal that demand is outstripping supply, which supports upward rent movement. Conversely, if vacancy in your suburb begins rising above 3 percent, an aggressive rent increase may cause a longer void period that costs more than the additional weekly income would earn.

Your property’s specific condition

Comparable properties are only useful if they are genuinely comparable. A freshly renovated two-bedroom apartment in Northcote commands a premium over an unrenovated equivalent on the same street. For a detailed look at how tenant expectations and rental values play out in specific inner-Melbourne locations, the renting Northcote market guide outlines typical tenant profiles and what drives rental premiums in that suburb.

What Notice Do You Need to Give for a Rent Increase in Victoria?

Under the Residential Tenancies Act 1997 (Vic), landlords must give tenants at least 60 days written notice before a rent increase takes effect. This requirement applies regardless of whether the property is managed directly or through an agent. The written notice must specify:

• The new rent amount
• The date from which the new amount applies
• The fact that at least 60 days notice has been given

Failing to give proper notice does not just expose you to a Consumer Affairs Victoria complaint — it also means the increase is legally unenforceable until notice is correctly re-issued, potentially delaying income by two or more months. Most experienced property managers build automated notice workflows directly into their systems. If you manage your own portfolio, understanding how rent collection software Australia landlords use can help you systematise these notice and payment workflows without relying on memory alone.

Rent increases during a fixed-term tenancy

Rent cannot be increased during a fixed-term tenancy unless the lease agreement specifies the new amount or the method for calculating it. A vague clause saying “rent may be reviewed” is not sufficient. If your current lease does not include a compliant rent review clause, the increase can only take effect at the next lease renewal, which reinforces the importance of drafting leases carefully from the outset.

How Much Should You Increase the Rent By?

Victoria does not cap the amount of a rent increase (unlike some other Australian states), but increases must not be excessive relative to market. Tenants can apply to VCAT for a rent increase to be reviewed if they believe it is above market value, and VCAT has the power to reduce it. This makes market evidence your single most important protection as a landlord.

As a practical guide:

1. Gather three to five genuine comparable rentals that have been leased in the past 30 to 60 days.
2. Calculate the median weekly rent of those comparables.
3. Assess your property honestly against those comparables — better condition, better amenities, or better location may justify a figure at or above the median; below-average condition should sit at or below it.
4. Factor in tenancy quality — a long-term, reliable tenant who pays consistently on time has genuine financial value. A modest discount to market for an excellent existing tenant is often more rational than maximising the headline figure and absorbing a vacancy and re-letting cost.
5. Document your reasoning — keep a file note of the comparables you used. If a VCAT challenge ever arises, this evidence is your primary defence.

What Are the Most Common Rent Review Mistakes Landlords Make?

Even experienced landlords fall into predictable traps when managing rent reviews. Being aware of them reduces the chance of an expensive error.

Skipping reviews for the sake of keeping the peace

Avoiding a review to avoid conflict is understandable, but it compounds the problem. According to REIV data, a landlord who misses just two annual review cycles on a Melbourne inner-suburb property can end up $50 to $100 per week below market, representing a loss of $2,600 to $5,200 per year in foregone income. A single larger catch-up increase also creates more tenant friction than a consistent annual adjustment would have.

Issuing notice too late

The 60-day minimum notice period catches many self-managed landlords off guard. Issuing notice 45 days before lease renewal means the increase cannot legally take effect at renewal — it pushes to 15 days after, creating an administrative gap and delaying income.

Using asking rents rather than achieved rents

Asking rents on listing portals are aspirational. Achieved rents — what tenants are actually signing leases at — can be 3 to 7 percent lower in a softening market. Your property manager should have access to recently signed lease data; if you are self-managing, ask your local REIV member agency for a rental appraisal based on actual transactions rather than current listings.

Ignoring the total cost of vacancy

A rent increase that causes a quality tenant to vacate is only financially justified if the new rent, factored over the remaining tenancy, exceeds the cost of the vacancy period plus re-letting fees. On a Melbourne inner-suburb property, a two-week vacancy alone typically costs the equivalent of a $20 to $40 per week rent increase maintained across a full year. Model the numbers before issuing any notice.

How Does Professional Property Management Support Rent Reviews?

A professional property manager brings market data, legal compliance, and negotiation experience to every rent review. They monitor comparable rentals continuously, track lease expiry dates, and issue legally compliant notices on schedule without relying on a landlord’s calendar. They also manage tenant communication professionally, framing increases in the context of market evidence rather than leaving landlords to navigate that conversation alone.

For landlords who prefer to self-manage but want systemic support, modern tools have become increasingly capable. Automated rent reminders, digital notice delivery, and market benchmarking features mean that self-managed landlords can now operate with a level of rigour previously only available through agencies.

Whether you manage one property or a larger portfolio, the discipline of reviewing rent annually, benchmarking carefully, and issuing notices correctly is what separates investors who consistently earn market returns from those who quietly underperform for years without realising it.

Rent reviews are not about squeezing tenants. They are about maintaining a fair, sustainable rental relationship grounded in market reality — one that works for both parties and keeps your investment performing as it should.
